I agree that, in large part, the parents are 100% at fault. They buy swiss cake rolls instead of apples, they buy potato chips as a 'snack' rather than celery. It's 100% their fault that their kids are fat, but it doesn't change the fact that a jumbo bag of potato chips is 99 cents and will last for weeks and weeks. A bag of carrots is $2.50 (at least here) and lasts a week or so before it spoils. If you have $50 a week to feed your family on you're going to go for what is filling and what costs less. White bread, enriched pasta, potato chips...all 100% unhealthy, but also cheap and filling and easy.
